It's not trivial if you get down to the PCB level. A good place to start is sites like: www.sparkfun.com www.makezine.com These sites will have tutorials and such. However, I would recommend you figure out what it is you want to learn from the experience. If it's making hardware, then focus on that, but start with more simple projects. Designing a PCB that has a fast running CPU and memory and such can be difficult. If it's creating the software, you'll save a lot of money and aggravation by purchasing an existing piece of hardware and running your own software on it. (for instance, the Android phones have touchscreens and displays, as do a lot of web tablets) [edit] Another option would be to make friends with a hardware person, give them lots of beer and coerce them into building it for you.
